DEVICE FORY HOLDING BACK THE CHANNEL-LIP OF A BOOT OR SHOE SOLE.

SPECIFICATION forming part of Letters Patent No. 266,018, dated October17', 1882.

Application iiled June 27, 188i.

To all whom lit may concern Be it known that I, GEORGE W. DAY, of

Haverhill, in the county of Essex and State of Massachusetts, haveinvented certain new and useful Improvements in the Manufacture of Bootsor Shoes, of which the following is a full, clear, and exactdescription.

This invention relates to the sewing of. the inner and outer soles tothe upper ot' boots or shoes by sewingmachinessuch as the wellknownMcKay7-using a horn, as it is termed, which enters into the boot andshoe and'is Iliade to follow around the upper, near the edge of theinner sole, carrying a thread which, with the thread of the needle oftheinachine, makes the stitch; and in relation to such machine-sewing ofboots and shoes it consists of the use of an inner sole having achannelin the inner surface running along at or near the edge where the line ofstitches is intended to be, and a lip which is integral with the solefor covering such line of stitches, in combination with a device to holdthe portion of said lip which is around the toe portion of the sole backand away and open from the channel at such portion of the sole in amanner to place it beyond a possibility of being disturbed in suchposition by the horn ofthe sewing-machine, while such horn is passingaround andabout such toe portion of the sole, whereby all danger ofstitching the lip at such toe portion to the sole and upper is avoided,and, in addition thereto, in a manner to be easily and readily detachedand removed, after the stitching of the sole is completed, for thepurpose of cementing the said lip over the row of stitches to cover andconceal the same, all substantially as hereinafter described.

lt also consists of a holder for the toe portion ofthe channel-lip,oftheconstruction hereinafter described.

In the accompanying plate of drawings, Figure l represents a face viewot' an inner sole, showing the channel andlip of its inner surface; Fig.2.a face view at the toe portion, showing a device to hold the lip inits turnedover position as applied; Figs. 8 and 4, sections respectivelyalong lines a: a and y y,

5; Fig. 7, a view similar to Fig. 3, showing a different form ofchanneling the inner sole; and Fig. S, a sectional view of the holdersimilar` to Fig. G, showing it as flat.

In the drawings, A represents an inner sole, which may be of any of theusual shapes and sizes; B, the inner face or side ofthe sole, at which,parallel, or nearly so, to the cdgea ofthe sole, the leather ischanneled in any suitable manner-as, for instance, as shown at bin Figs.l, 2, 3, and 4 of. the drawings, or as shown at bin Fig. 7, which is across-section ofthe soleand corresponding to this channel b the sole hasa lip, c, which is integral with it. The lip is preferably prepared withcement before sewing it, with the outer sole, to the upper, and when sosewed the row of stitches runs along the channel, near the outer edgethereof, O, a sheet-metal plate. This plate, along its edge d, is oftheoutline ofthe toe portion of a boot or shoe sole,'and its under side, f,about such edge, is concave, as at g, for a portion ofthe width ot' theplate, andthe plate, at or near the central portion thereof, is providedwith a sharp-pointed prong, h, which projects from the under side and ina line from the toe or front end, 7a, ot' the plate toward the rear orheel end thereof, and in a line substantially parallel with the underface of the plate. This plate C is the holder for the toe portion of thelip, and it is of suitable size to surround and lie, by its edge d, uponthe saine inside of the channel, and in this position it is held byinserting its prong h into the body proper of the sole, as shown in Figs3 and 4t more particularly. By this means the lip at the toe portionofthe solle is held in its turned-over position while the horn ofthesewing-machine is passing around the saine, and held againstaccidentally or by any other possibility being stitched to the sole insuch sewing operation.

After the sewing is completed the plate O is removed, and by forcing ittoward the toe end of the boot or shoe, and the lip is turned down andsecured in the channel l) over the stitches, all as ordinarily.

The plate O can have its under side made flat; but it is preferable tohave it concave, as shown, as it tends to the better hold and preventthe lip from being displaced when stitch- IOO ing the soles, asdescribed. In Fig. Sis shown in cross-section the holder C as made Hat.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. The device, substantially as shown and described, adapted to be'detachably secured to the sole of a boot or shoe, near the toe portion,and to hold back the channel lip or ap While the upper inner` sole andouter sole are bein gsewed together, substantially as set forth.

2. The holder-plate G, having; a prong, h, all substantially as and forthe purpose described.

3. The holder-plate C, having a prong', h, and concave portion d,substantially as and for 1 5 the purpose described.

In testimony WhereofI have hereunto set my hand in the presence of twosubscribing witnesses. 'i

GEORGE W. DAY.
